How can I approve translations at my plugin…
=>
“Hopefully one of the GTE:s (General Translation Editor) should find some time to have a look at your translation. If it’s overall OK, then, most probably, they’ll make you PTE (Project Translation Editor) for that particular project, so that you can continue maintaining the same plugin/theme translation, going forward.”
I’ve download the translation files (po/mo) directly and added to my installation – works well.
